Ego death and stream entry is it the same thing?

I was wondering if ego death and stream entry is the same? During what i call 'ego death' or 'experience of pure consciousness', i emptied out and saw the internal galaxy images. Insights came although it felt too much to comprehend. I was speechless. Basically it was inconceivable. It lasted 6 hours and more I couldn't sleep after. After that my life changed significantly. I still have issues with self esteem but much less.
